This invention relates generally to shavmg brushes, particularly to fountalnor reservoir brushes which mvolve means whereln certain operations thereof" cause soap, either I 7 in liquid or paste form,'to be discharged unto A further object of the invention is to pro-' vide in a brush of thattype wherein a slidmg piston is employed for causing the dischargeof soap into the brush,improved piston means so constructed as to preven-t air gaining access to the soap-reservoir; means V to prevent soap interfering with free action? of the piston, and means to hold .the piston agains't becoming detached from its operatin device. I

A further object is to provide a brush of the character briefly. stated of that type f wherein a piston or plunger is employedffor causing the soap to be, discharged into the brush, andwhich is featured with means for.

preventing rotation of the plunger. 1

A still further object resides in an improved brush head construction which greatly facilitates recharging the same with paste lapsible tube container.

Still further and-particular objects reside in the construction of 'a pressure operated brush head which is of extremely simple constructiom which is composed of but few readily assembled parts, which has these parts'so arranged and assembled as to mini mize the opportunity for wear, breakage or derangement, which is capable of operation in such manner as to minutelycontrol the "quantity of soap dischargedinto'the bristles, which may be readily taken apart for, cleaning or soap replenishing operations, and

which will prove highly practical and efficient". v

The brushof the present invention comprev hends'a head composed of separable parts, one of 'which contains areservoir for the reception of shaving soap or paste and from which the paste is to be discharged into the brush bristles. The other part'carrieswith it the ily separated, when desired, for cleaning or replenishing purposes, and are soconstructed as to render impossible to improperly Ieadjust these parts with respectto each other. Associated withone of these parts is a safety device whichnormally operates to prevent discharge of the paste or soap, whereby to obviate the possibility of leakage or untimely discharge ofthe soap or paste.

an improvedconstruction of head which per-- mits of ready application thereto ofithe threaded end of the familiar collapsible pastetube. While this structure permits of th'eready filling of the reservoinit also permits of thehead being associateddirect with 'acollapsible tube so thatthe latteigif desired,

The walls of this bore near one end are preferably tapered as represented at 8 and merge with acomparatively small opening 9 centrally and longitudinally disposed in the head and constituting a discharge opening. The walls at the opposite end of this bore are threaded as at 10, to accommodate the threads 11 upon the exterior of a discharge nozzle forming part of the well known collapsible paste tube 12. To this end,

The brush proper is represented at 13 and w the bristles thereof may 'be secured together at their inner ends inanypreferred manner, andattached to the discharge end ofthe head .6. However they may be .secured together,

This plate .isprovided with an opening 16 corresponding in sizeqto the discharge opening 9,.sothat when these openin-gsare aligned, free passage of-paste therethrough is-permi tted. The outer end of the plate 15 is secured to one end of a.flat-s pring 17,, the opposite end of said'spri-ng being an-' .I .chored in the exterior surface of the .head 6.

The head 6 is recessed as at 18 toipermit of :the samebreadth as the spring 17. op

I By closing the channelonslot at the enter end of the-plunger, soap is prevented gaining access toand clogging the channel;

The plunger, ror at least theinner or operative end thereof, -fits snugly-with the walls of the reservoir 7' toprevent soap working between the said walls .and the ,plunger body.

this construction, danger of clogging of,

the plunger is eliminated, and, furthermore, such fitting of the parts prevents air gaining access to the reservoir, whereby-drying or hardening ofthesoap is obviated. f Theztight fitting of the diaphragm -or.-plate 21 ;serves..

The shell20 fisathen applied to the head .6 by screwinggan'd -the plunger .22 will be aligned with the reservoir 7 To operate the brush thus charged, it is but necessary to rotate the plate or cap 24, as the screw 23' carried there by will at once operate to drive the piston or plunger 22 into the reservoir 7. Such operation, however, will not cause discharge of any paste from the reservoir, owing to the fact that thc'plate 15 normally closes the discharge end of the reservoir. It is necessary, therefore, that the valve 15 be moved so that the opening thereof willbe brought into alignment with the discharge end of the reservoir before the paste can be forced into the brush[ This permits of the quantity of soap to be accurately governed, and pre eludes accidental discharge of soap which would be caused by merely rotating the plate. Furthermore, the lathering operation may be greatly facilitated, as initially the cap may be rotated with the valve closed so as to exert a high degree of pressure upon the contents of the reservoir. When it is desired then to discharge soap into the bristles, it is but necessary to slightly depress the spring 17 and immediately upon the openings becoming in registry, the soap will be, forcibly ejected into the brush.

As has been heretofore stated, the head 6 may be used directly with the soap container 12, if desired, and the check valve will prevent entry of any soap to the bristles should the compressible tube be accidentally squeezed.

While the above is a description of the invention in its preferredembodiments, it is nevertheless to be understood that-variations in the details of arrangement, the combination and assemblage of parts may be readily resorted to without departing from the-spirit of the invention as defined in the claim.

Having thus described my invention, I

o claim A dispensing device of the class described comprising a reservoir member having a longitudinal bore, a shell detachably secured to one end of said reservoir member and having a lateral internally projecting tooth, a plunger member slidably engaging said bore and provided with a longitudinal groove cooperating with said tooth to prevent relative rotation between said plunger and member, said plunger having an internally threaded bore, a cap member rotatably mounted on the outer end of said shell, a threaded stein rigidly secured to said cap and threaded in. said plunger bore-whereby when said cap member is rotated relative to said shell, said plunger will be advanced or retracted in said reservoir member, substantially as described. In testimony whereof I afiix my signature.
